Corrosion of second degree of unsp scapular region, sequela

This code signifies a second-degree chemical burn (corrosion) that occurred in an unspecified area of the shoulder blade region, and the patient is now presenting for treatment of the long-term effects or complications of that injury. A second-degree burn involves damage to the epidermis and dermis, typically presenting with blistering, pain, and redness. The "sequela" indicates that the initial acute injury has healed, but residual problems persist.

Use this code when documenting the follow-up care for a patient who previously sustained a second-degree chemical burn to an unspecified part of their scapular region, and they are now being treated for a chronic condition or complication directly resulting from that past injury. Examples include scar revision, chronic pain management, or addressing functional limitations stemming from the old burn.

• Always use a sequela code (ending in "S") when the patient is being treated for the residual effects of a past injury, not the acute injury itself.
• Ensure documentation clearly links the current condition to the previous second-degree corrosion of the scapular region.
• If the specific location on the scapula is known, a more precise code should be selected (e.g., T22.661S for right scapular region).
